Mack Pack

Does the Mack Pack work well without a topping lift on the Freedom rigs? Do
those with
Mack Packs use their boom end support for the aft end of the pack? Does their
system
require new holes in the carbon fiber mast? What else would I have to consider
in thinking
about installing the Mack Pack on a F-33?

I installed mack packs last year and have
a season on them. They work very well and have made it a pleasure to go out for
short sails. A couple of things to note:

Depending on your angle to the wind
when you raise the sails and how you have the lazy jack lines cut and adjusted
(angles, tension) relative to the full battens the battens can hang up when
raised as with any lazy jacks. After some experimentation with slacking the
sheet and watching the sail when raised this became a non issue. No need to
slack/pull back the lazy jack lines.
Normal installation requires 3
attachment points on each side of the mast. The top is a hook and the lower 2
are twists like for a dodger. All are with rivets. On mine I sealed the hole
edges with epoxy before rivets. This is how I did mine after much investigating
on the location and whether this could affect the mast and deciding the small
holes in these locations (like the ones for the sail tracks). Having used them
for a season the top hooks are important and I can’t see a way around
that. The lower 2 on each side I think could be left out and shock cord from
one side around the mast to the other might suffice (the lower shock cord might
need some downward pull to keep the zipper operating freely but I don’t
think). I should have tried this but my sailmaker and mack said it wouldn’t
work well without them. I think they’re wrong and it would reduce the
number of holes. Anyway you could try it and add them later if needed.
The look is not quite like in the
brochures/pictures. It tends to be a bit baggy to allow extra space to keep it
easy to drop into and the extra lines in the lazy jack part look a bit odd to
me. I can email you pictures if you like or we can talk by phone.

Forgot to answer about the topping lift.
When I added my mack packs I also added boomkickers so there is no problem . In
any event the lazy jack part of the mack packs would support the booms but they
recommend attaching a topping lift or the main sheet when stowed.
Another note is most of the time you can
leave the mack pack on the mast hooks while sailing but downwind there is
strain on the lower hooks so they need to be released. Of course for performance
its better to take them off.

I installed the Mack Pack on a F36 with a solid vang. Works well. A
few points: On the 36 at least, there never was a topping lift. The
lazy jacks served that purpose and could still as well wih the Mack
Pack if you are so inclined. The Mack Pack requires 6 holes in the
mast, 3 on each side of the sail track. Drill and tap an 8/32
machine screw and epoxy in place. Re-think the lazy jack leg
spacing along the boom. Mack equally spaces the down legs along your
boom length. If you have a full roach, full batten main, you will
not have enough support at the boom end. Since the sail is already
supported at the mast track, Favor the spacing to the aft end of the
boom. Consider extra length primary lazy jack lines led aft along
the boom to cleats for adjusting purposes. finally, there is the
hanging laundry effect. The boat just doesnt look clean with the
cover hanging while sailing. But, you get used to it. In reality, in
the time and effort it takes to stow the sail and zip up the Mack,
you can retrieve and put on a normal sail cover. All things being
equal and had I not needed a new sail cover, I would have upgraded
the existing lazy jack system and altered the sail cover.

Interesting. I find the time it takes to
stow the sail with the mack packs to be dramatically less then with sail ties
and sail covers. (And on the 33 there are two) I imagine it partially depends
on the how tight the original sail covers were. Used to take me about 20
minutes or so to stow both sails and get the sail covers on and involved a lot
of long reaches (and I’m short). With the Mack Packs takes me about 5
minutes total.

Hi. I have a Mack pack on my Freedom. Great invention. Pull one zipper and your off. Have also Gaurhauer rigid vang, a must in my opinion for it to work best.

Hi Again, Just want to add that my Mack Pack sail cover does not hang when sailing. It lies against sail. Had HUGE roach ,a la Hobie cat, put in. Great !

I had Doyle Stack Pack on my Tartan 30. Loved it. Unfurl took 1 minute. Furling took about 2-3 minutes.

It makes a one hour sail something I didn’t think twice about because it was so easy.

The Stack Pack required only 2 attachments on each side of the mast. One just above the boom and one 1/2 way up the mast.
